The reflex liquid level gauge has a sturdly contructed body, with the glass and cover securely held by U-bolts maintain a hermetic seal
This type of level gauge features several parallel grooves cut into the glass surface tha is in contact with the liquid. The resulting prismatic diffraction cause gases to appear white by reflection: liquids black by absorption thus the level od even transparent liquids can be cleary observed.
low-medium and high-pressure type may be used according to application conditions and units may be manufactured using carbon steel, stainless steel or a wide variety of other material for parts in contact with the liquid. Type HRG reflex gauge have a number of futther advantages including light weight, availability of long visible lengths and low price
